view (removed an extra tag )

Prior, every single test was creating four `ProjectMember` objects, each
of which created one `User` record, even though each test only used
_one_ of those Users, if any.

Now each test only creates the single user record it needs, if it needs
one. This shaves minutes off of each spec file changed here.

Also incorporates the review into this, mainly spec changes.

The user has the rights of a public user execpt it can never create a project,
 group, or team. Also it cant view internal projects.
